Early Life of Prince Sado and the Seeds of the Prince Rice Chest Tragedy
Prince Sado, born Yi Sun (이선) in 1735, was the second son of King Yeongjo and Royal Noble Consort Yeong. His elder brother, Crown Prince Hyojang died prior to Sado’s birth. As Cown Prince, but for his death, Sado automatically became the heir apparent.
Initially, this appeared a solution for the Joseon dynasty’s future. But Sado’s childhood soon began to show cracks. King Yeongjo’s exercise had a strict hand, hot tempered, being rigid in discipline and demanding required his perfection. And Sado fell short of that standard.
The king made pointed ridicule of his son publicly, scoffed Sado would not attend royal events, and frequently shamed him in front of courtiers.
Yeongjo could not support developing confidence and self-efficiency in the boy, because he taught him fear and shame.
The boy began to develop anxiety and timidity, searching for warmth and validation from the king-yet he received little emotional bond from his mother, who was loyally afraid of the king and conformed to this rules.
The gross instability of Sado’s childhood would rotten into the disaster of Prince Rice Chest.
Marriage to Lady Hyegyeong and Testimonies of the Prince Rice Chest Story
By the time Sado was just eight years old, he was married to a fellow child, Lady Hyegyeong. Initially they were playmates, but ultimately they became a royal couple in the traditional sense. Later, Lady Hyegyeong will be of utmost significance to our understanding of the Prince Rice Chest history.
In 1805, decades after the execution, she produced The Memoirs of Lady Hyegyeong (한중록, Hanjungnok). It remains our principal resource on Sado’s life, equal parts affection for him, and horror. She recounts Sado as a man destroyed by abuse and mental illness, but terrifyingly violent.
Her memoirs allow us to learn the psychological condition of the palace, the cruelty of King Yeongjo, and what led to the execution of Prince Rice Chest. Without Lady Hyegyeong’s account, Sado could have seamlessly passed into rumor.
First Signs of Madness: Early Decline of Prince Sado
Sado’s early health troubles included fainting spells at age nine, which disappointed his father. In 1749, he became regent at age 15, entrusted with state affairs. But nothing pleased Yeongjo. Every decision Sado made was ridiculed.
In 1752, tragedy struck when his beloved sister Princess Hwahyeop died. The same year, Sado reportedly read the Taoist text Okchugyeong, which triggered hallucinations of the Thunder God and an intense phobia of storms and engraved characters.
By 1757, the deaths of two adoptive mothers—Queen Inwon and Queen Jeongseong—pushed him further into instability. Both had been kind to him, and losing them stripped away his last sources of affection.
Lady Hyegyeong’s memoirs describe the turning point: Sado’s behavior shifted from anxious to violent. He beat servants, carried severed heads to shock attendants, and raped women in the palace. This violence built the foundation for his eventual confinement and the Prince Rice Chest death.
Court Politics Behind the Prince Rice Chest Execution
The Joseon dynasty suffered from factionalism and Sado’s instability created a political tool. There were two factions—the Noron and Soron—clashing for superiority; King Yeongjo was affiliated to the Noron and they regarded Sado as dangerous and unworthy of the throne.
There were many rumors about Sado: he killed eunuchs, he threatened his half-sister Princess Hwawan, he raged around the palace drunkenly; even if not all of these were true and some were exaggerated, the effect was the same: fear permeated the court.
The King’s situation was dire:
- if he executed his son, he risked destroying the royal line.
- if he did nothing, the whole dynasty could come crashing down under Sado’s violence.
The eventual action—sealing Sado in the rice chest—was as much
The Prince Rice Chest Death: Eight Days of Agony
On July 4, 1762, King Yeongjo called his son to the court. He commanded that Sado be put into a wooden rice chest (뒤주). The box was a grain storage container approximately 1.5 meters in length, not meant for a person.
Once sealed in, the chest had no room to move or breathe, no food, no water. It was hot outside, even more so inside that box.
Sado spent a total of eight days in the chest. Witnesses heard him begging for water and mercy. On July 12, the chest was opened. The crown prince was dead; from dehydration, suffocation, and heat.
The Prince Rice Chest execution—a royal prince suffocated inside a wooden box—now occupies a place in Korean history.
Aftermath of the Prince Rice Chest Tragedy
Fifteen days after, King Yeongjo restored Sado’s titles and status posthumously to carry over succession through his grandson Yi San, who became King Jeongjo (r. 1776–1800), one of the most popular kings in Joseon.
Jeongjo expressly acknowledged his father, erasing King Yeongjo’s attempts to erase him. He built shrines, respected the spirit of Sado, and initiated reform movements based on tragedy.
Lady Hyegyeong’s memoirs further influenced perceptions of Sado. By covering both violence and victimization, she neither trivialized nor concealed Sado’s behavior.
Was the Prince Rice Chest Death Madness or Conspiracy?
Historians disagree on this :
- Madman theory: Sado was suffering from a severe mental disorder – perhaps schizophrenia or bipolar disorder. This explains delusions of grandeur and hallucinations, where Sado would have paranoid delusions and violence.
- Political conspiracy theory: Some factions at court either overstated or fabricated his crimes to justify his exile.
- Two tragedy theory (the most accepted): Sado’s violence was real, but his violence was the product of years of abuse, trauma, and neglect. He was a perpetrator and a victim, ruined by a society that had no concept of a mentally ill person.
This debate is at the core of the Prince Rice Chest story – was he a monster, or was he made a monster?
The Prince Rice Chest in Culture and Memory
The sad history of the Prince Rice Chest has been reproduced in numerous shapes and forms like:
- Memoirs: The Memoriam of Lady Hyegyeong stands as the definitive recount.
- Film: The Throne (2015) sparked Sado’s struggle with Yeongjo, and brought Sado’s story to global audiences.
- Television Dramas: There are many Korean historical dramas retelling the story ultimately warning against power strife and familial betrayal.
- Literature: Numerous novels and essays shared their retelling as it relates to Sado being a villain, being a victim, or both.
At Seosamneung Royal Tombs where Sado rests with his family the rice chest holds as a cemetery object but elicits the image of a pale. People ponder the atrocities and challenges faced of Korean history.
Comparisons: The Prince Rice Chest and Other “Mad Royals”
This Prince Rice Chest story is often contemporized with insane royal cases throughout the world:
- Caligula of Rome – notorious for cruelty, licentiousness.
- King George III of England – mentally ill but sympathetic.
- Ivan the Terrible of Russia – bloodthirsty, paranoid, disorganized.
It is not the manner of massacre – not by sword or poison – which separates the Prince Rice Chest execution, but a punishment by way of confinement in a rice chest which symbolized both familial treason and a political necessity.
Modern Lessons from the Prince Rice Chest History
The tragedy raises modern questions:
- How should societies address mental illness, especially among leaders?
- Can trauma and abuse create cycles of violence?
- How do politics manipulate personal suffering for power?
In Korea today, where mental health is still stigmatized, the Prince Rice Chest execution is often revisited as a reminder of what happens when silence, shame, and cruelty replace compassion.
Conclusion: The Lasting Legacy of the Prince Rice Chest
The Prince Rice Chest event was more than a spat between family members; it was a clash of power, politics and human weakness.
Simultaneously, the young Prince Sado was simultaneously a victim and a perpetrator – a young man burdened by his father’s expectations, traumatized and tainted by his violence.
Prince Sado’s death in the rice chest is one of Korea’s most painful visual symbols. Conversely, his son, King Jeongjo, took his father’s tragedy of losing a son and used it as an opportunity to grow – he was a reformist and one of Korea’s greatest kings.
The Prince Rice Chest story remains with us; it forces us to confront our own discomfort of mental illness, abuse and the implications of power.
It is a legacy of humanity that sits behind royal designations, and memorializes brutality of power alongside the successes of history.
